Q:What is the role of the contactor
machine tools and various electrical units such as power load, contact Not only can turn on and off the circuit, but also has a low voltage release protection.
Q:What are the classification of contactors?
arc time is relatively long, in order to fully release the circuit The remaining energy. The combustion of the arc produces high temperature and strong light, the surface of the contact has a serious ablation,
Q:AC contactor technology development
Semiconductor contactor: The semiconductor contactor is a contactor that performs current operation by changing the conduction state and the open state of the circuit circuit.
Q:Determine whether the AC contactor can cut off the short circuit current?
When the coil is energized, the static core produces electromagnetic attraction, and the moving core is sucked
Q:A brief introduction to the power contactor
The AC contactor relies on a spring return after power failure. The other half is the activities of the core, the structure and fixed iron core, to drive the main contacts and auxiliary joints of the short
Q:What are the types of AC contactors?
In order to quickly extinguish the arc when the break, usually contactor are equipped with arc extinguishing device, the general use of semi-sealed vertical seam clay hood, and with a strong magnetic blown arc.
Q:Three-phase AC contactors have several useful clients?
. And note whether the contact point is normally closed or normally open. If there is self-locking control, according to the principle of the line on it.
Q:What causes the AC contactor to be damaged
. Increase the power capacity, replace the line repair control contact 3. Replace the coil
Q:What is the effect of the contactor coil parallel capacitor?
Capacitors at both ends of the voltage can not be special changes, and the capacitor can delay and reduce the coil's reverse electromotive force, Reduce interference, extend the life of contacts.
Q:What is the power contactor
The main contact is generally only normally open contacts, and auxiliary contacts often have two pairs of normally open and normally closed contact, small contactor is often used as an intermediate relay with the main circuit
